## Long description

The BlueOptics QSFP-40G-CU5M InfiniBand/fibre optic cable 5 m Black is a 5-metre, high-density direct-attach cable with QSFP male connectors on both ends. Designed for short-reach, high-throughput links in data centres and network racks, this cable supports 40 Gbps class interconnects and provides a compact, low-latency connection between compatible switches, routers and server adapters. Its black jacket and flexible construction suit standard cabling environments where reliable signal integrity and easy routing are required.
Advantages
The cable delivers consistent high-speed data transmission with minimal signal loss across its 5 m length. QSFP connectivity ensures compatibility with 40 G-class ports and InfiniBand interfaces, while the direct-attach design eliminates the need for transceivers, reducing power consumption and component count. The construction balances durability and flexibility to allow tidy cable management in dense equipment racks.
Suitable for
 Short-reach connections between switches and top-of-rack routers
 Server-to-switch links in high-performance computing (HPC) environments
 InfiniBand fabrics and clustered storage interconnects
 High-density cabling in data centre racks and network closets
Key specifications
 Connector type: QSFP male to QSFP male
 Length: 5 metres
 Data rate class: 40 Gbps-compatible direct-attach
 Cable colour: Black
 Cable type: Direct-attach copper/active cable for short-reach links (InfiniBand/fibre optic compatible use cases)
 Form factor: Compact QSFP for high-density installations
How to use
Install the cable by aligning and inserting each QSFP male connector into the corresponding QSFP port on your networking devices until it clicks into place. Ensure devices are powered down or that hot-plug procedures recommended by the equipment manufacturer are followed if connecting live. Route the cable to avoid sharp bends and excessive tension; maintain the minimum bend radius specified by rack and device manufacturers. After connection, verify link status in device management interfaces and confirm negotiated data rates and link health.
Usage recommendations
Use this 5 m QSFP direct-attach cable for short, high-speed links within the same rack or between adjacent racks. Avoid prolonged exposure to temperatures or environments outside typical data centre ranges, and keep connectors free of dust when not in use. For longer distances or fibre-only infrastructure, consider optical transceiver solutions matched to your equipment.
